FIBROUS BUILDING MATERIAL.

To all whom 'it may concern? Be it known that LALEXANDER P. Wrirrn, a citizen of the United' States, residing. at Caldwell, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Fibrous Building Materi l, of `which the following is aspecification.

` Accordinglygthe object ofthe present inf ployed chiefly metal lathing and which lends itself readily v ents Nos. 1,049,631v dated January material having This invention relates to a novel and prac-- tical construction of building materialhaving the same general characteristics, ob]ects,

and uses as 4the forms ofbuilding materiall disclosed iii and covered by my formerPat- 7,1913, 1,049,630 'dated January' '7, 1913,' and 1,049,629 dated. January 7, 1913, but having improved features of construction possessing special'advantages.

vention lis to provide anew and practicalV construction of building material to be emas a substitute for wooden and foi-'use in the capacity of a mold to temporarily give form to the plaster, while at the same time affording a substantial support formetallic members which will. not onlyI reinforcethe walls but constitute permanent supporting? elements therefor. Othervmore are to provide a Ibuilding little expansion and contraction. Also, the improved material when used' as -lathingis intended to provide a 4specific objects i multiplicity of keying seats for the plaster,

and .tov hold themetallic members in such a wayuthat the'plaster may readily key aboutthe'same Y f 0 With these and other ob]ects in view,-the invention consists in the novel construction,

combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

For the purpose of illustrating the -invention, certain practical embodiments thereof are shown in thevaccompanying drawings, in which Figure 1 is a perspective view of one 4form of building material embodying the present invention.

responding parts in the several figures of the drawings.

The distinguishing characteristic of the present invention is the employment of a fibrousl body material having a multiplicity of corrugations. These corrugations maybe of various shape, size, and extent. may be'uniform or non-uniform, and may be -produced in any suitable manner, but for the purposes of illustration,

invention shown in the several figures ofl the drawings have corrugations of a unithe forms of the form-character and extending throughout .the entire area of the sheet. VFor instance,

as shown in -Figs. l to 6. inclusive of the They drawings, the fibrous bodymaterial, desigy nat-ed -by thereference letter A, is illustrated as having a regular and continuous series of rounded corrugations-a, and .the grooves or valleys of these corrugations lend them selves admirably as casings for satisfactorily.

seating the metallic members or rods which constitute theV main supportingand reinl forcing means for the wall or ceiling.

According to the suggested embodiment drawings, the metalin the grooves of certain of the corruga# tions, and may bev'conveniently fastened to the fibrous body sheet-A by staples or equivalent fastening means c, 'so that the body sheet will constitute a temporary support for Vholding the metallic members in posi tion on the wall or ceiling until the plaster has set and'hardei-ied thereon'. In this ai'- rangen'ient,' all of the metallic members or i rods b are'eXposed at the same side of the.

body sheet, butit will be obvious that this may be altered, under some conditions, by locating some of' the metallic members or rodsat one side of the sheet, and others at lthe opposite side of the sheet, as suggested in Fig. 3 of the drawings.

-. In addition-to utilizing'the grooves of any desired number of the corrugations'as cas- 1 ings for seating the metallic members or rods, the grooves of the lcorrugatioiis may also have the im ortant function of receivin cementitious fillings which add strength an sheet and may enable it to better .perform its function as' a support oi' carrier vfor the'met'allic members., This combination may be employed as shown in Fig; 4, wherein `cementitious fillings d are placed incertain grooves of the sheet at the same side thereof, thus-forming eementitiousf rods and the metallic rods alternated therewith, or as shown in Fig. 5, where the me'- tallic members and cementitious rods arealternated respectively at opposite sides of the' sheet, or as shown in Fig. 3, to be. furtherreferred to.

Another special form of the invention thatv may be utilized in a practical manner'is the one'shown in Fig. 6 of the drawings, wherein the fibrous body sheet A is .illustrated as being formed withcorrugations of special design. These corrugations all project to one side ofthe plane of the sheet, but essentially consist of4 alternating rounded and angular elements e and f, producing an effect of thev rounded elements being disposed in regular.- spaced relation with angular keyin' grooves;

g therebetween and adapted to be fi led iwith a cementitious filling h which gives great strength to the material throughout .and greatly stifens the rounded elementse, any

number of. which rounded 4elements are adapted to receive therein the metallic mem-,

.bers or rods b. Also, the said rounded elef ments e are formed with contracted or nar-v rowed mouths or openingswhich 4are narrower than the diameter or width ofthe me-' tallic members or rods, so-that the latter are retained in place without supplemental fas-- tening or retaining means, while atthe same l'time the plaster element willbe'admitted y vinto the grooves within the-rounded elements' v for locking engagement .with the metallic members or rods.

ings, wherein a more positive and d ente retention of the metallic members may beaccomplished by welding or otherwise fasten-Q ing thereto as at w, suitable cross pieces.; ot-

metal or equivalent material extending over.- one face of the body sheet.;.. Thesecross pieces y' also increase the reinforcement for j the cementitious material as well as assist? ing in the support of the latter. i In all embodimentsof the invention, the

y fibrous body material preferably consists of 'a sheet of paper such as ordinary corrugated. cardboard. Also, it may be found prefer-v able in. carrying vout the invention to treatl the body material lwith. any -of the we lll known waterproofing or fireproofinglcompounds, but regardless'of this feature it .will `be observed that' according to1 thepresent However, -a modificationof this idea isshown in Fig'. 7 ofthe draw#v invention in v:all of its forms, a corrugated body sheetisfemployed and metallic mem# manner as to be disposed forzengagementrby and vwlth the plasterv as it sets. and hardens,
